Oil loading arm product introduction and composition

Oil transfer arm product introduction and composition Oil transfer arm is an essential supporting equipment at the oil terminal, used to connect oil and gas from cargo ships to the terminal storage and transportation equipment. It plays an important role at the terminal. So what are the components of the oil transfer arm?

The oil loading arm is composed of the following parts: column, support, inner arm, outer arm, swivel joint, balancing system for balancing the arm assembly, with a main balance and a secondary counterweight, and a locking device for keeping the arm in the retracted position. First, the column of the oil loading arm: this secondary assembly is self-supporting and installed on the dock. Second, the support: it bears the total deadweight of the arm, the maximum wind load, and the weight of the cargo in the arm, and serves as a passage for the fluid from the arm to the pipeline on the dock side (or vice versa). Third, the inner arm: the inner arm is connected to the top of the column, including the protruding part of the main counterweight beam. Fourth, the outer arm: the outer arm connects the inner arm and the ship. There is also a swivel joint: the swivel joint is composed of multiple rotating parts, which are used to connect the inner and outer arm parts to perform related actions. The sealing ring of the swivel joint adopts a specially designed and unique structure to ensure sealing. Different swivel joints are used in different parts. Balancing system: the secondary counterweight is fixed on the top of the outer arm to balance the outer arm. The main counterweight is fixed on the lower part of the inner arm to ensure the correct balance of the loading and unloading arm assembly. Locking device: The loading arm is locked in the static (receiving) position by a simple mechanical device. Force state of the ship's manifold: When the loading arm is completely balanced in the unloaded state, the forces acting on the tanker flange or manifold are only the forces acting on the cargo in the arm and the wind load. Depending on the inclination of the outer arm, the torque applied to the manifold may change from positive to negative. Arm action: Since the arm is designed to be balanced in the "unloaded" state, it is necessary to make the arm completely empty before connecting to or removing from the ship, otherwise it is dangerous. Removable swivel joint system: The removable swivel joint system allows the inspection and replacement of the seal ring without further disassembly of the arm during maintenance, so it is unnecessary to prepare lifting equipment and reduce downtime. Drainage: Depending on the cargo, operating conditions, port regulations, etc., optional equipment related to various drainage systems can be supplied, and it can also be designed according to user requirements.

Shanghai Guanzhuo Enterprise Development Co., Ltd. is a manufacturer of dock and petrochemical supporting products. It has rich experience in the production, installation and maintenance of oil transfer arms. Each set of our products must undergo water pressure tests, balance commissioning and other tests before leaving the factory, and low-temperature tests must be carried out for low-temperature gas transportation. The company has strong technical strength and owns many product patents. For example: utility model, ZL200920070395.7, a teaching position controller for oil transfer arms; a safety protection device for oil transfer arms, patent number ZL200920070394.2, a smart oil transfer arm ZL201020238280.7, etc. As an important product series of the company, oil transfer arms are widely used in various oil terminals across the country, and the products are also exported to Asia, Europe, America, Africa and all over the world. They are widely praised. We look forward to the coordinated development of experts and industry professionals from all walks of life to build more, better and more excellent engineering projects.
